Description

<p>The effect of cylindrical wing with longitudinal grooves and streamwise grooves to the performance of the magnus windmill is clarified by using different surface shape of rotating cylinder. The rotation number of windmill was measured using a wind tunnel at wind speed of 8~20 m/s. A cylinder rotation is 400~1600 rpm. As a result, it was revealed that a longitudinal groove cylinder has a higher rotation number of windmill than streamwise groove cylinder.</p>
